Understanding Keratoconus & the Importance of Early Diagnosis
Corneal Cross-Linking
Not long ago, a diagnosis of progressive keratoconus left patients with few treatment options.
Today, Avedro’s Photrexa® Viscous (riboflavin 5’-phosphate in 20% dextran ophthalmic solution), Photrexa® (riboflavin 5’-phosphate ophthalmic solution), and KXL® system are FDA-approved for use in corneal cross-linking and provide patients with a one-time, minimally invasive therapeutic treatment to limit the progression of their condition
What is Keratoconus?
Keratoconus
[ker-uh-toh-koh-nuh s]
Keratoconus or “KC” is a non-inflammatory eye condition in which the normally round dome-shaped cornea progressively thins causing a cone-like bulge to develop. This results in significant visual impairment.

Importance of Early Detection
KC is a progressive condition which worsens over time, so early diagnosis is critical
